摘要：

For better yields and higher quality, manufacturers must consider statistical process control (SPC) and statistical quality control (SQC) as standard tools for understanding, validating, and improving processes in all areas of manufacturing. Online SPC software excels at monitoring production processes in real time. It uses parameters that have a direct, understandable effect on the process. On the other hand, offline SQC software is a decision-support tool that allows the analysis of process behavior and is essential to detecting differences over time. Together, SPC and SQC software are a powerful tool that can help cut costs, reduce rework and scrap, increase yields, meet tighter specifications, reduce process variation, and improve the bottom line.
